Scacchiera deformata


20

Questa sfida riguarda la costruzione di una scacchiera in cui la dimensione quadrata, anziché essere costante su tutta la linea, segue una certa sequenza non decrescente, come descritto di seguito.

La scheda è definita in modo iterativo. Una tavola di dimensioni n×n viene ingrandita a dimensioni estendendola verso il basso ea destra di uno "strato" di quadrati di dimensione , dove è il massimo divisore di non superiore a . I quadrati nella diagonale sono sempre dello stesso colore.(n+K)×(n+K)KKnn

In particolare, considera la lavagna con i colori rappresentati come #e +.

  1. Inizializza la scacchiera su

    #
    
  2. La scheda finora ha dimensioni 1×1 . L'unico divisore di 1 è 1 e non supera . Quindi prendiamo ed estendiamo la tavola aggiungendo uno strato di quadrati di dimensione , con in diagonale:1K=11#

  3. La scheda costruita finora ha dimensioni . I divisori di sono e il divisore massimo non superiore a è . Quindi di nuovo , e la scheda è estesa a2×221,221K=1

  5. La dimensione è . Ora k = 2 , perché 2 è il divisore massimo di 4 non superiore a 4×4K=2244 . Si estende con uno strato di spessore2, formato da quadrati di dimensioni2×2, con colore#nella diagonale:

Si noti come i quadrati aggiunti più di recente, delle dimensioni 3×3 , abbiano lati che coincidono parzialmente con quelli dei quadrati aggiunti in precedenza delle dimensioni 2×2 .

La sequenza formata dai valori di K non è decrescente:

1 1 1 2 2 2 2 3 3 3 3 4 4 4 6 6 6 6 6 6 ...

e non sembra essere nell'OEIS. Tuttavia, la sua versione cumulativa, che è la sequenza di dimensioni della scheda, è A139542 (grazie a @Arnauld per averlo notato).

La sfida

Input : un numero intero positivo S rappresenta il numero di strati nella scheda. Se preferisci, puoi anche ottenere S-1 invece di S come input ( 0 -indexed); vedi sotto.

Output : una rappresentazione in arte ASCII di una scheda con livelli S

  • L'output può essere tramite STDOUT o un argomento restituito da una funzione. In questo caso può essere una stringa con newline, una matrice di caratteri 2D o una matrice di stringhe.

  • Puoi costantemente scegliere due personaggi qualsiasi per rappresentare il tabellone.

  • Puoi scegliere costantemente la direzione della crescita. Cioè, invece delle rappresentazioni di cui sopra (che crescono verso il basso e verso destra), è possibile produrre una qualsiasi delle sue versioni riflesse o ruotate.

  • È consentito lo spazio trailing o iniziale (se l'output è attraverso STDOUT), purché lo spazio non sia uno dei due caratteri utilizzati per la scheda.

  • Opzionalmente puoi usare l' input " 0 -indexed "; cioè, prendi come input S-1 , che specifica una scheda con livelli S

Vince il codice più breve in byte.

S-1

Senza il finale Y, questo restituisce un elenco di elenchi di numeri interi, ma questo è fuori specifica per questa sfida.

Spiegazione

Questo programma funziona in tre fasi.

  1. KK
  2. Genera una scacchiera per ognuno di questi con la dimensione del riquadro di K
  3. Lavora attraverso l'elenco delle scacchiere, sostituendo ogni volta la sezione in alto a sinistra della scacchiera successiva con quella esistente.

Fase 1

1                 | Start with 1
           Ʋ³¡    | Loop through the following the number of times indicated by the first argument to the program; this generates a list of values of k
 S                | - Sum
        Ɗ         | - Following three links as a monad 
  ÆD              |   - List of divisors
    >Ðḟ½          |   - Exclude those greater than the square root
         Ṁ        |   - Maximum
          ṭ       | - Concatenate this to the end of the current list of values of k 
              Äż$ | Zip the cumulative sum of the values of k with the values

Fase 2

      ʋ/€ | For each pair of k and cumulative sum, call the following as a dyad with the cumulative sum of k as the left argument and k as the right (e.g. 15, 3)
Ḷ         | - Lowered range [0, 1 ... , 13, 14]
 :        | - Integer division by k [0, 0, 0, 1, 1, 1, 2, 2, 2, 3, 3, 3, 4, 4, 4]
  Ḃ       | - Mod 2 [0, 0, 0, 1, 1, 1, 0, 0, 0, 1, 1, 1, 0, 0, 0]
   ^þ`    | - Outer product using xor function and same argument to both side

Fase 3

   /  | Reduce using the following:
ḷ""   | - Replace the top left portion of the next matrix with the current one
    Y | Finally join by newlines

Penso che chi chiede effettivamente i personaggi #e +. Ma wow, ancora impressionante, ne ho capito circa la metà. E come programmate anche in una lingua simile? C'è una tabella di personaggi e il loro significato da cui hai appena copiato?
Fabian Röling,

@ FabianRöling L'OP afferma che due caratteri erano accettabili. C'è un buon tutorial introduttivo per Jelly su github.com/DennisMitchell/jelly . Se conosci Python, anche la fonte è abbastanza leggibile. Anche con il tutorial e gli elenchi di atomi e Quicks, ho scoperto che ci è voluto un po 'di tempo e in alcuni casi riferimento alla fonte per farmi girare la testa.
Nick Kennedy,
